We performed a hospital-acquired methicillin-resistant Staphylococcus aureus molecular study in Buenos Aires city. Four clones were found harboring the transposable elements Tn4001 and Tn5405 and the erythromycin resistance determinants ermA and mef(E). Of the isolates, 73% belonged to a clone found previously in the city of Córdoba, which showed an epidemic behavior initially attributed to the widely disseminated South American clone.
